Astronomy 10 Chapter 11 1. Both used to be normal stars but the white dwarf ran out of hydrogen, they are both subjected to gravitational theories. A Neutron star is a fluid of neutrons, as hot at its surface as the inside of the sun and has a greater magnetic field. 3. Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle.

The theory of Black Holes and its process is one of the most unique studies of the universe, in that with each discovery made, we un-lock closed doors to knowledge of how the universe was made. In 1798 a French Mathematician Pierre Simon de Laplace came up with the first theory of a Black Hole. He agreed with Newton, that when enough mass is added to a star like the sun, the gravitational pull would become so great that the escape velocity would equal the speed of light. Therefore, the star would blink out and become an invisible star. More than a century later, Einstein, came up with the theory of relativity.

Describe two ways in which gravity has a part in the life-cycle of a star- Gravity pulls the dust and gas in the nubula together, and compresses them so much that the inside becomes hot enough for fusion reactions to start. Gravity also pulls the remains of a red giant together after fusion reactions have stops. This forms a white dwarf. Theories about the universe- 1. What does red shift tell s about distant galaxies?
If light can’t escape from a black hole, then it must be invisible - therefore how can we know that the black holes exist? Black Holes, if theories of their existence are true, black holes are the most powerful force in the known physical universe. Many people are familiar with the term black hole, but few people actually know anything about them. A black hole forms as a result of a massive star running out of fuel to burn (Black Holes, Relativity, and Fate of the Universe by Eric Chaisson, p.193). Once the star is no longer exerting outward force by burning off gases, it begins to collapse under its own intense, inward gravity (Chaisson, p.193).
There are many theories about what is going to happen, including: galactic alignment, prophecies of Armageddon, impossible scientific experiments, the Mayan-predicted apocalypse, and many more. Many scientists believe that galactic alignment in 2012 is going to bring natural and even cosmic disasters on earth. Galactic Alignment is when the sun is in position between the earth and the black hole in the center of the Milky Way galaxy. Many people believe that when the sun and earth become aligned with the black hole in the center of the Milky Way galaxy, this will bring about the end of the world in 2012 because it
Theorists claim that the extremely high levels of radiation would have cooked the astronauts if they had gone through it. 4. Slow Motion walking. In order to explain how NASA mimicked the low gravity conditions on the moon theorists contend wires and hidden cables were used to show the astronauts floating
I. Gas Cloud A. Our sun, like all other stars in the universe, began its life as a cloud of dust and gas B. Immense clouds, spanning light-years, but very sparse (several hundred atoms per cubic cm) 1) Earth’s surface = 1.0x1017 or 100 quadrillion atoms per cubic cm—NASA C. The cloud begins to swirl and coalesce inwardly under the relentless force of gravity D. With collapse now under gravity’s pull, the dust and gas particles begin to generate frictional heat II. Protostar (100,000-50million years)—NASA A. The kinetic energy generated by these particles rubbing together (friction) releases infrared energy B.
Astronomy is a natural science which is the study of celestial objects, the physics, chemistry, and evolution of such objects, and phenomena that originate outside the atmosphere of Earth, including supernovae explosions, gamma ray bursts, and cosmic microwave background radiation. cosmology, is concerned with studying the universe as a whole. Astronomy is one of the oldest sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, and Maya performed methodical observations of the night sky. However, the invention of the telescope was required before astronomy was able to develop into a modern science.
